I have those modules, 5 of them (from ebay), but have not used them yet. I have used http://www.ebay.com/itm/131380498361 (3.3V version) and they work perfectly.
If you are looking for a potted version, check these ones: http://www.ebay.com/itm/131424221544

#14540 Hi all, I took the advice mentioned earlier in this thread and used a 5V USB adapter. Combined with an LM3940 and a 100uf cap on the output, it was quite easy to setup.

The ESP flashed twice, and the access point appeared in my PC wifi list... Great.

My question is with regards to actually using the ESP with an USB FTDI board for debugging/programming.

I'm thinking I should simply connect the FTDI ground to the 5v USB ground (which the ESP and reg are grounded), and the tx/rx to the ESP. Is it as simple as this? (I do software, hardware is basically a guess) .

I do have a level shifter breakout, but many posts around the net remark on the fact the tx/rx/gpio are 5V tolerant. I'm not too worried about destroying the $10 worth of equipment (worst case), I'm more concerned with connecting it to my PC.

Cheers, Chris.

EDIT: solved, after rounding up a few Arduino circuits sharing supplies I found my answer. (Also had RX/TX wrong).
